Remnick to Obama: focus on climate change NOV 12 2012

Barack Obama can take pride in having fought off a formidable array of deep-pocketed revanchists. As President, however, he is faced with an infinitely larger challenge, one that went unmentioned in the debates but that poses a graver threat than any "fiscal cliff." Ever since 1988, when NASA's James Hansen, a leading climate scientist, testified before the Senate, the public has been exposed to the issue of global warming. More recently, the consequences have come into painfully sharp focus. In 2010, the Pentagon declared, in its Quadrennial Defense Review, that changes in the global climate are increasing the frequency and the intensity of cyclones, droughts, floods, and other radical weather events, and that the effects may destabilize governments; spark mass migrations, famine, and pandemics; and prompt military conflict in particularly vulnerable areas of the world, including the Middle East, Southeast Asia, and sub-Saharan Africa. The Pentagon, that bastion of woolly radicals, did what the many denialists in the House of Representatives refuse to do: accept the basic science.

The economic impact of weather events that are almost certainly related to the warming of the earth -- the European heat wave of 2003 (which left fifty thousand people dead), the Russian heat waves and forest fires of 2010, the droughts last year in Texas and Oklahoma, and the preelection natural catastrophe known as Sandy -- has been immense. The German insurer Munich Re estimates that the cost of weather-related calamities in North America over the past three decades amounts to thirty-four billion dollars a year. Governor Andrew Cuomo, of New York, has said that Sandy will cost his state alone thirty-three billion. Harder to measure is the human toll around the world-the lives and communities disrupted and destroyed.
